DAVID Returning on eunnnna'rrns, MIeIIIeAN, ASSIGNOR TO THE RUNYEN MANUFAC- TURING 0 9;, OFEG' To all whom it may concern: Be it. known 'thatI, DAVID RUNYEN, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of-Michigan, have invented certain new and useful Improvements in -Grease-Dispensing Mechanism; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a grease dispensing mechanism and has for its ob ect and purpose the simplification of the construction and operation of grease dispensing devices whereby the same may be produced at a much lower cost than. heretofore and, at

thesaine time, the mechanism will be rendered more durable and eilicient. For the attainment of. these desired ends I have embodied'my invention as disclosed in the accompanying drawings in which;

Figure l is a vertical section through one 'form of my invention.

Fig. 2 is a plan view thereof with parts broken away and shown insection. r

Fig. 3 is an elevation, parts also being broken away and shown in section to disclose the interior structure.

Fig. 4, is a vertical sectional view substantially on the line H of Fig. 6, illustrating a slightlymodified form of construction.

Fig. 5 is a side elevation of said modified form. i p a Fig. 6 is a plan view with parts broken away andshown in section and,

Fig. 7 IS a fragmentary plan view also partly in section of the modified construc tion of cabinet.

Figs. 8, 9 and 10 are views similar to Figs.

1, 3 and2 of a second modified form of construction of cabinet.

Like reference characters refer to like parts throughout the several views of the drawings.

The grease is adapted to be contained,

within a can or other suitable receptacle, preferably acylindrical can 1 having a-bottom 2 the upper end ofthe cam being prac-' tically closed by a segment 3 permanently closure of the upper end of the can and at secured in place and to which a second segment 4 is pivotally connected to complete the 1) names; manic-an, A coieroan'rion or MICHIGAN. annesn-nrsrnnsme MECHANISM.

permit the entrance of grease upper end entering loosely within the ring a'member 5 froi 6 heretofore described. In the lower part of the can a casting 10 is located on the upper side of which a conical tapered seat 11 is made against which the lower edges of the barrel. 9 normally rest, The casting 10 has an extension 12 which passes through a side of the can 1 as shown and to which any suitable flexible hose conduit may be attached, a passage 13 in said casting and extension 12 thereto being made which coinniunicates with the interior of the barrel9. A pair of upwardly extending lips 14 are formed integral with the casting 10 and eX- tend above the conical seat 11 for a short distance into the lower end of the barrel.

A foot member including a horizontal base 15 with two separated vertical ears 16 is secured to the can by means of bolts 17 which pass through said ears and also through laterally extending parts to the casting 10 thereby rigidly connecting the-casting in place at the same tiinethat the foot member is secured in position. The extension 12 to the casting passes between the 'ears 16. A piston rod 18 is located Within the barrel 9.and passes through the member- 5 its lower end carrying a suitable valveless piston 19. while its upper end is equipped with an operating handle 20.- Between cast- In operation, on. the upward stroke of the piston the barrel raised until its upper end engages with the lower side of the tween the lips 14- for the entrance of grease into the passage 13 and into the barrel as" the upward stroke is continued. The lips 14 hold the lower end of the barrelf froin ids disengagement with the casting lb -and on the downward stroke of the piston the barrel, at its lower end, seats tightly against 100. member 5 thereby-leaving two openings be;

the conical seat 11 and. the grease within the barrel and passage is forced outward through the extension 19, and any condult that may be connected thereto.

The modification shown in Figs. 4 to 7 inclusive is similar in substantially all respects except that the extension 12 to the casting 10 shown in Fig.1 is not passed through the side of the can as before but, as shown. in 19. in Fig. 4, it is located within the can there being a tube 22 secured in the end of said extension and communicating with the passage 13, the upper end of the tube passing through the member 5 which is slightly modified in term from the me1nher 5. Any suitable flexible hose connection to this tube may be made above the end of the can. This obviates the necessity of passing the part 12 through the side of the can and at the same time the foot member need not be divided to make the two ears 16; but as shown in Fig. 5 the horizontal member 15 has a single integral vertical section 16 lying alongside the can and adapted to be connected to the inner casting 10 by bolts 1? as before, The elimination of the outer ex- I tension 12 permits a better engagement of the foot with the horizontal :toot portion 15. Otherwise the construction .is identical with that shown in Figs. 1 and 3 inclusive and the principle of operation is the same in both constructions.

In Figs. 8 to 1.0 inclusive a second and preferred modification is shown. In this construction a base 23, of cast metal, is used to which the lower edges of the can 1 may be secured in any suitable manner, as by soldering. The base has depending annul .1 sides 24: which serve to elevate the can a short distance. A hollow projection 25 has an opening 26 in one side thereof the lower end of the barrel 9 passing over said pro- 1ection and in its lowermost position seats against a conical taperedseat 27 similar to the seat 11 heretofore described. jlhe projection 25 has 'a stop for the downward thrust ofthe'piston 1.9 whereby the piston rod l8 may be of the same diameter throughout its length. A passage 29 leads from the opening 26 to a point outside of the can termihating in an outwardly extending boss 30 in theupper side of which an opening is made whereby the tube 22* may be threaded therein Integral also with the base foot are ledges 31 one to each side of the boss 30. Of course, it is understood that while the tube 22 may be secured as shown a hose such as indicated at 12 may be connected either above or below the upper member 5 which is slightlyfmodified from the members 5 and 5. in the constructions previously described, sons to support the upper end of the tube 22*.

The operation of the mechanism in this construction is identical inpractice with ing secured at the bottom of the receptacle below the segment, a lateral extension to the casting, a conical tapered seat on the upper side of the casting, there being a passage through the casting from the upper side within the limits of said seat and through said lateral extension, a tubesecured to said extension a member secured to the. segment, an annular ring depending from said memher through the segment, a barrel. normally resting at its lower end on the tapered seat of the casting, and at its upper end entered a short distance into the ring, guiding means on the casting entering into the lower end of the barrel, :1. piston in the barrel, a rod connected thereto and extending through said member, an operating handle on the upper end of therod, and a foot member.
